Answer:
Step-by-step explanation:
So the point-slope formula looks like this:
= any y point on the line
= any x point on the line
= the slope
And hey, look, we're already given all that information!
So we can just plug those values into the equation:
(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)
Answer:
a) α should be larger than β
Step-by-step explanation:
a) Refer to the diagram attached to the bottom of this answer. Given that the tumor is cancerous (that is saying that α happens), there are other events different than β in that event space, so β should be smaller than α.
b) Using the diagram again, we can see that the probability of β happening is the product of α and the probability that the coin shows tails, which is 0.5, then:
β = 0.5·α
which proves β is half of α, hence α is larger.
